当鼠标悬停显示为块时，Css ul显示为none

I'm working on a dropdown box but the only thing that doenst want to work is when I hover over the word Info in the unordered list the dropdownbox is not displayed.

我在做一个下拉框，但doenst唯一想做的是当我在无序列表中鼠标移到Info时下拉框就不会显示。

I know I have display:none; in ul style but can you change that to display:block; when hovered over the word info?

我知道我展示过:没有;在ul样式中，但可以将其更改为display:block;什么时候在信息这个词上徘徊?

2 个解决方案

#1

use #Menu before your css class names : DEMO

在css类名称之前使用#菜单:演示。

like: #Menu li:hover > ul {display:list-item;}

比如:#Menu li:hover > ul {display:list-item;}

NOTIC: css Class names are Case-Sensitive

NOTIC: css类名是区分大小写的

#2

I am thinking this is because the html code contains an inline display:none. In the inner <ul>, we should remove <ul style="display:none;"> in the above html.

我认为这是因为html代码包含一个内联显示:none。在内部

，我们应该删除
